VAPORIZER AND VAPOR-BURNER.

Application filed December 14, 1911.

To all whom it mayconcern Be it known that we, Anonr'n C. BEHNKE andALBERT J. Barman, citizens of the United States, residing at Valders I0., in the county of Manitowoc and State of WVisconsin, have invented acertain new and useful Improvement in Vaporizers and Vapor-Burners, ofwhich the following is a full, clear, concise, and exact description,

reference being had to the accompanying drawing, forming a part of thisspecification.

()ur invention relates to kerosene gas heat ers and has for its objectthe provision of a new and improved apparatus of this character in whichkerosene may be used as a fuel for heating purposes, but in which thiskerosene is first vaporized by the action of the apparatus itself, andthis vaporized kerosene is then combusted.

In the preferred form of the invention, we utilize a suitable tank wherethe kerosene may be stored at a suitable elevation so that this kerosenemay be fed under pressure to a coil of pipe forming a vaporizingapparatus in which to properly vaporize the kerosene. The vaporizedkerosene is emitted within a chamber containing the coiled pipeaforesaid and there burns to supply heat and to likewise heat thekerosene in the pipe so as to vaporize it to issue in vapor form fromthe nozzle. In starting the apparatus it is found very simple to permitsome of the kerosene to flow through the vaporizer and issue from thenozzle openings in liquid form which falls to the bottom of theapparatus and may there be properly ignited to supply the initial heatnecessary to vaporize the kerosene in the coil. After the initialvaporization the vapor issuing from the nozzle becomes ignited and theaction of the apparatus there after is continuous and the (flegrce ofheat supplied may be suitably regulated as desired.

The invention will be described in detail by reference to theaccompanying drawing illustrating one form of carrying out theinvention, in which:

Figure 1 is a sectional view illustrating the improved apparatus, andFig. 2 is a detail view of the nozzle or vaporizer.

In the illustration is set forth a suitable retainer 1 within which theapparatus is supposed to be mounted, and to which access may be had bymeans of the door 2. This retainer may form part of a suitableSpecification of Letters Patent.

oven, a portion of whose walls are illustrated. A pipe 3 leads from akerosene tank not shown, from which lwrosene is fed through the pipe 3,the valve l, and into the pipe 5, the elevation of the tank serving toplace the kerosene within the pipe 5 under sutlicient pressure toproperly operate the apparatus. A controlling valve (3 connects the pipe5 with the pipe 7 and this controlling valve 6 utilized to regulate theflow of kerosene into the apparatus.

lVithin the retainer 1, we provide a suitable burning chan'lber 8 withinwhich a cylindrical tube 9 open at both ends is mounted. \Vithin thiscylindrical tube the pipe 7 extends and this pipe after runningsubstantially the full length of the tube 9 is bent in a spiral mannerback toward the left of the apparatus, the pipe thus forming coils 10,10. At the extreme left end of the apparatus the last coil is bentdownwardly and then toward the right, terminating in a nozzle 11, whichnozzle may be constructed for instance in the form shown having two endsof pipe 12, 12, provided with suitable dis charge openings 13, 13. Thevalve 4 is designed to entirely prevent or permit the flow of kerosene.

Now in order to start the apparatus the valve 4 is opened to permit asmall amount of kerosene to flow through the openings 13, 13, and fallto the bottom of the tube 9. This liquid kerosene is then ignited and inthe course of the combustion serves to supply sullieient heat to thekerosene at the nozzle to vaporize the kerosene therein so that thiskerosene issues from the openings 13 in vapor form and this vapor isignited by the burning kerosene. The increased heat causes an increasedflow of this vapor and the burning vapor, when the n'laohinc isoperating normally, fills the entire interior of the tube 9. Ileat isthus given out by this burning vapor and this heat at the same timeserves to heat the kerosene in the coils so that it may continue toissue as a vapor and the apparatus may continuously operate as a vaporburning device. Openings 14, il l are provided in the tube 9 to admitadditional air to the interior of the tube 9 to cause completecombustion and also to permit heat to easily travel therethrough. Bymeans of the valve (3 the supply of kerosene may be regulated so thatmore or less heat may be given out by the machine as desired.

The opening 15 in the left hand Wall of the retainer 1 permits air toenter for the process of combustion, and the products of combustion areWithdrawn through the tube or stack 16.

It is of course apparent that many changes and modifications may be madeof the apparatus herein described, but the specific form herein shownWill serve to indicate the invention disclosed herein.

Having, however, thus described a specific form of carrying out theinvention, the following is claimed as new and desired to be secured byLetters Patent:

A liquid fuel burner consisting of a combustion chamber, a hollow tubeopen at both ends disposed therein and having apertures through theupper portion thereof, a coiled pipe disposed throughoutthe length ofsaid ADOLPH C. BEHNKE. ALBERT J. BEHNKE. Witnesses:
